Bill, It really depends on what is being remapped. In the case of the KS ROM being remapped by the MMU, then you are correct that the "speed hit" is offset by the gain achieved by the speed difference between 32-bit RAM access and ROM access. Other uses of the MMU, however, can and do slow the machine down. For example, using a program like Enforcer (which is a developer tool that uses the MMU to detect memory access to areas where a well-behaved program should not be) will slow a machine down. Similarly, an attempt to implement a form of Virtual Memory on the Amiga will slow the machine down. Hope this clarifies things a bit. …BobR
